These arrays are used by the Musepack decoders, the MPEG audio decoders
as well as qdm2 and up until now, these arrays might be initialized more
than once, leading to potential data races as well as unnecessary
initializations. Therefore this commit ensures that each array will only
be initialized once.

This avoids code duplication in the functions used to initialize them
and allows to remove an AVOnce.

The CONFIG_ name-space is set by configure, so its better to use a
different prefix here.
This also unifies the encoder & decoder define that is used

This table is used only by mpegaudiodsp and mpegaudioenc. Separating
it allows dropping some dependencies from mpc[78] and qdm2.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.
